COM connector
General Purpose I/O
Connect one alarm sensor device and/or one relay-driven device to the GPIO connector via a 4-
pin 3.81 mm pitch terminal plug:
●
To connect one alarm sensor, insert the 2 wires into INA (pin 1) and INB (pin 2) of the 4-pin
plug.
●
To connect one relay-driven device, insert the 2 wires into OUTA (pin 3) and OUTB (pin 4) of
the 4-pin plug.
